       isosize - output the length of an iso9660 filesystem


       isosize [options] iso9660_image_file


       This  command  outputs  the  length  of  an  iso9660  filesystem  that is contained in the
       specified file.  This file may be a normal file  or  a  block  device  (e.g.  /dev/hdd  or
       /dev/sr0).   In  the  absence  of any options (and errors), it will output the size of the
       iso9660 filesystem in bytes.  This can now be a large number (>> 4 GB).


       -x, --sectors
              Show the block count and block size in human-readable form.  The  output  uses  the
              term "sectors" for "blocks".

       -d, --divisor number
              Only  has  an  effect  when -x is not given.  The value shown (if no errors) is the
              iso9660 file size in bytes divided by number.  So if number is the block size  then
              the shown value will be the block count.

       The  size  of  the  file (or block device) holding an iso9660 filesystem can be marginally
       larger than the actual size of the iso9660 filesystem.  One reason for  this  is  that  cd
       writers are allowed to add "run out" sectors at the end of an iso9660 image.


       The  isosize  command is part of the util-linux package and is available from Linux Kernel
       Archive ⟨⟩.
